When you installed J2SDK, I am assuming that JRE also got installed with it, and JAVA_HOME variable has been set. Also, Add the java/bin directory to your PATH environment variable. Just check in command line that when you type "java" in front of command prompt, you are getting the java usage details.
Hope this will help,
Modesty is good!! But remember, all your life other people will try and take your achievements away from you, don't make it easy for them.
I've noticed that sometimes when you install a different/newer version of the java products you need to re-install any others. The error is about the JVM so try reinstalling the JVM off the media (test env first!)
Mark Hummel: Yes I know there is a problem with my Java uninstallatin and installation but still don't know why this happened.
Ogut Kutlu: Thanks for your solution. It works great!. now i wonder to choose my java. there are so many Java.exe. c:\j2sdk1.4.2_10\jre\bin\java.exe c:\program files\java\j2sdk1.4.2_10\jre\bin\java.exe and the other more after search. think this one is the problem. Thanks to you!
There are both same version, you can choose whatever you want. Normally i choose first one. Since web console needs java 1.4, you must not choose 1.3 version sdk or jre comes with service desk, if they are listed.
